The national anthem/song of any country should be having a power to unite its citizens. If it divides, it should not be adopted.
No communiy/sect of our country have ever raised objection over "Jan Gan Man", "Satya Mev Jayate", "Vasudev Kutumbkam" etc. If some sections r not confortable singing "Vande Maataram", we should not politicize the matter & in the interest of our great country, must do some research to know why "Vande Maatram" is not acceptable to them..!!
